Description:
------------
When I return a graph of objects that has circular references (a tree of categories, for example), the soap server gets stuck in an infinite loop/recursion and hangs.
Reproduce code:
---------------

Expected result:
----------------
The server should use mutliRefs and create references to each object. Each object instance would be serialized one time and given a unique ID, which is then pointed to each time an reference to that object is encountered.
Something like this:
<getThingWithParentResponse>
<result href="#object1"/>
</getThingWithParentResponse>
...
<multiRef xsi:type="ThingWithParent" id="object1">
...
<parent xsi:nil="1"/>
<children>
<child href="#object2"/>
</children>
</multiRef>
<multiRef xsi:type="ThingWithParent" id="object2">
...
<parent href="#object1"/>
<children xsi:nil="1"/>
</multiRef>
Actual result:
--------------
php hangs
